My Epson R-300 stopped working the other day. I got some error message complaining about parts had come to the end of their life and to contact Epson. After a search on google I found out how to re-set the printer, and found out about ink pads inside. I took the little hoze out the back and was amazed how much ink it wastes! I now save all the waste ink and put it back in the black ink tub. Works a treat.
